How to Clean Cache on Xiaomi Redmi 9A: A Complete Guide with Pictures and Tips

Why Redmi 9A is slowing down and how cache affects performance

Have you noticed that your Xiaomi Redmi 9A has become slower to work, applications open for a long time, and memory is constantly running out? 90% of the time the cache is to blame - temporary files that the system and programs accumulate in the process of work. At 4/64 GB of modification Redmi 9A, the problem is especially acute: after 3-4 months of active use, the cache can take up 3-5 GB of precious space.

There are three types of cache: system (created by Android and MIUI), applications (each app stores its own temporary data), and browser (cache sites in Chrome, Mi Browser and other browsers). Cache cleaning does not delete your photos, contacts or messages - only unnecessary temporary files, but there are nuances: for example, after cleaning the Google Play Store cache, you will have to re-enter your password, and in games some graphics settings may reset.

In this article, you will find 5 proven ways to clean up cache on Redmi 9A, from standard MIUI tools to hidden features for power users, and we will also show you how to automate the process and avoid the most common errors that lead to even larger brakes.

Method 4: Cleaning the system cache with Recovery Mode

If Redmi 9A is getting unbearably slow and standard methods are not helping, try clearing the system cache through Recovery Mode, which is more radical but secure - it doesn't delete your data, only temporary system files.

Instructions:

1. Turn off the phone.
2. Press the Power + Volume buttons up at the same time and hold for 10-15 seconds until the Mi logo appears.

5. Confirm the action and wait for the completion (it will take 1-2 minutes).
6. Reboot your phone with Reboot → Reboot to System.

1. Open the Security app (the shield icon).
2. Go to Optimize or Cleaner (depending on the MIUI version).
3. Slip on Deep Cleaning → Cash applications.
4. Turn on the Auto Clean option and select the frequency (recommended 1 time per week).

• ⏰ It works in the background, does not require your participation;
• 🛡️ It does not delete important data, only a secure cache;
• 📊 It shows how much memory is released after each cleaning.

⚠️ Note: In some versions MIUI Autocleaning may conflict with Google Play Services, causing increased battery consumption. If after turning on the autocleaner, the phone becomes faster to discharge, turn it off and use manual methods.

What to do if after cleaning the cache problems remain

Cache cleaning doesn’t always solve the brake problem on the Redmi 9A. If the phone is still slow, check out the following:

1. Free memory: On Redmi 9A With 4GB of RAM, you need at least 1GB of free RAM to work stably. Close background applications through Recent Apps (button "□").
2. Background Processes: Open Settings → Applications → Application Management → Run and disable auto-run of unnecessary programs.
3. Viruses: Scan in Security → Antivirus. Some malware masquerades as cache and consumes resources.
4. Updates: Check firmware relevance in Settings → About Phone → System Update. At the time of writing, the latest stable version for Redmi 9A is MIUI 14.0.2.

If none of these methods worked, consider the following radical measures:

• 🔄 Reset to factory settings (save data in advance!);
• 🔧 Reverse to the old version MIUI (If the brakes started after the update);
• 🛠️ Replacement of memory chip (in service center if phone is older than 2 years).
